T 0 (ZZZ whom it may concern:

Be it known Rana and J .K'MES A. Knxuss, citizens of the United States,and residents of East Greerr ville, in the county of Montgomery and.State of Pennsylvania, have invented a new and Improved Shuttle, ofwhich the following is a full, clear, and exact description.

The object of the invention is to provide A a new and improved shuttle,more especially designed for use in silk ribbon looms, and arranged totear the filling thread in case the shed is not fully open or clear,owing to extraneous matter causing a tangle of some of the warps. Forthe purpose mentioned, use is made of a spring-pressed locking devicefor the quill, and normally inactive, to allow free rotation of thequill, but when an obstruction in the open shed engages the lockingdevice, then the latter is released to lock the end of the quill andthus hold the same against turning, to tear the filling thread, thusstopping further formation of the weave.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a plan view of the shuttle; Fig. 2 is a transverse sectionof the same on the line of Fig. 1, and showing the shuttle in positionon the open shed; Fig. 3 is a sectional side elevation of the same onthe line of F l, the quill spindle and quill being removed; Fig. i is aplan view of the shuttle, parts being in section, the quill spindle andthe quill being removed; Fig. 5 is a side elevation of the quillspindle; and Fig. (i is an end view of the spool or quill.

The body A of the shuttle is provided with the usual bow-shaped frontportion B, in the opening of which extend the bearings c, C extendingangularly from a metal plate C, secured to the body A of the shuttle,the bearing C being fixed to one side of the frontportion B, while theother bearing C is resilient. The bearing C is provided with a recess ordent C for the reception of one end D of the spindle 1), having itsother end formed with an angular arm D engaging a correspondin socket(1*, formed in the resilient bearing C the said arm D and the socket Cholding the spindle that we, WELLINGTON N.

I against turning. On the spindle D is mounted to turn loosely the spoolor quill E, carrying the filling thread E, which after unwinding fromthe spool or quill passes through the eyes G, G and G and finallythrough the eye H, fixed in the front portion B of the shuttle body. Theeyes G, G are held on the ends of springs G G attached to the frontportion B, while the eye G is hung on the front portion adjacent to theeye H, fixed in the front portion B of the shuttle body. A spring brakeI held on the plate C, bears in the usual manner against the filling onthe spool or quill E, to retard the turning of the latter with a view toprevent the filling from unwinding faster than required.

The ends of the spool or quill E are provided with slots or recesses E,of which the recesses at the right hand end are adapted to be engaged bya locking device, controlled by ext aneous matter on the warp, ashereinafter more fully described. The locking device, as shown, is inthe form of a locking bar J, mounted to slide lengthwise in bearings Kand K, arranged on the plate 0, the bearing K being elongated to alsoallow up and down swinging movement of the locking bar J, the otherbearing K acting as a fulcrum. The bar J is pressed on in the directionof its length by a spring L, and one end J is adapted to abut against astop N on the plate C. The other end of the bar J is provided with anL-shaped lockii g arm J (see Fig. 4), guided in a slot C in the bearingC, and adapted to engage a recess E in the adjacent end of the spool orquill a. The bar J is provided with a curved portion or arm J extendingnormally a short distance (about an eighth of an inch) below the shuttlebody A, to thus extend into the path of any tangled warps or otherextraneous matter, so that when the shuttle passes through the shed (seeFig. 2), and the arm J 3 comes in contact with the tangled warps orother extraneous matter, then an upward swinging motion is given to thelocking bar J, to disengage the end J from the stop N, to allow thespring L to move the locking bar J in the direction of the arrow a, andthus engage the locking arm J 2 with the recess E in the spool or quillE, to hold the same against rotation. When this takes place, the fillingthread F is broken and thus further weaving is prevented, as no fillingis paid out by the shuttle. The operator now stops the loom, removes theobstruction that caused the tangle, and then resets the locking bar J bymoving the same in the opposite direction of the arrow at and abuttingthe end J against the stop N. On moving the locking bar J in the inversedirection, the spring L is placed under tension, to readily shift thelocking bar J in the direction of the arrow a, as soon as the nextextraneous matter on the warp P actuates the locking bar J, as abovedescribed.

By constructing the bearings C, C and the spindle D in the mannerdescribed, the spindle can be quickly removed or replaced, forexchanging empty spools or quills E for filled ones, and by having thearm l) engaging the socket C the spindle D is held against turning. Thespool or quill E is preferably provided at both ends with recesses E, toallow of slipping the spool or quillv E in position on the spindle l),to locate either recessed end adjacent to the locking arm J forengagement by the latter.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

1. A shuttle for looms provided with a locking device normally held inan inactive position, and adapted to be released by obstructions in theshed, to engage and lock the quill against rotation and thus tear thefilling thread.

2. A shuttle for looms, provided with a spring-pressed locking bar forlocking the quill, the locking bar having a projecting portion forengagement by obstructions in the shed, and a stop for normally holdingthe locking bar in an inactive position and under the tension of itsspring.

3. A shuttle for looms, provided with a quill spindle, having one endprovided with an angular arm, a metal plate secured to the shuttle andbearings for the ends of the spindle extending angularly from the saidplate, the bearing for the angular arm end being free and resilient andprovided with a recess for the reception of the said angular swingingmo\'*ement of arm, the other bearing being tired and provided with arecess for the other end of the spindle to rest in.

4. A shuttle tor looms, provided with a spindle having recessed ends, alocking bar having a locking arm for engaging one of the recessed endsof the said spindle, the said locking arm having a projecting portionfor engagement by obstructions 1n the open shed, a stop for one end ofthe said locking bar to abut against, and a spring connected with thesaid locking bar.

5. A shuttle for looms provided with a spring-pressed locking bar forengaging and locking the quill, hearings in which the lock ing bar ismounted to slide, one of said bearings being elongated to permit up anddown the locking bar, the said locking bar having a projecting portionfor engagement by obstructions in the shed, and a stop for normallyholding the locking bar in an inactive position and under the tension ofits spring.

6. A shuttle for looms provided with a quill having recessed ends, ametal plate secured to the shuttle and carrying the bearings for thequill spindle, one of said bearings being provided with a slot, alocking bar mounted to slide in bearings on sand plate and having alocking arm guided in said slot and adapted to engage a recess in theadjacent end. of the quill, a spring exerting tension on said lockingbar in the direction of its length, and a stop on said plate againstwhich the other end of said locking arm is adapted to abut, the saidstop hol-d ing the locking bar in inactive position and with the springunder tension, the said locking bar having a projecting portion forengagement by obstructions in the shed.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
